We study a system with unlimited service potential where all service requests are served in parallel. The entire system itself becomes unavailable for a random period of time at the first instance that the system becomes idle. A queue builds up while the system is unavailable, and then all waiting customers enter the system simultaneously-each to its own processor-when the system becomes availa...

In this paper a M /G(a,b)/|1 queuing system with multiple vacations, delayed service and setup time is considered. If the queue size is < ‘a’ after a service completion or after a vacation termination, the server goes for multiple vacation. Also after serving M batches continuously even if sufficient number of customers are there in the queue, the server goes for a vacation with probability α j...

Project preemption allows resources flow passively from one project or task to another. Due to high-cost and high-risk characteristics of software development, project preemption might have a significant impact on the ultimate completion time of a software project. This article examines the feasibility of the Taguchi’s parameter design to achieve robust resource assignment for multiple software...
